I've heard the same thing Barry.. don't know where the stats are found

No supporting stats. Lycoming has researched it and it's a myth.
You can find the info in their tech briefs on their website.

I heard it "around the airport" c1980. If there are stats, they are old.

About all I can add is that one of the locals had the engine drop to idle at
the first power reduction--probably at the crosswind turn--the clevis
connecting the throttle to the carburetor came loose. IIRC, he made a
successfull landing on the airport.
